CHARLES A. ALEXANDEESON, E NEW YORK, N. Y., AssrGNonTo EMMA W. D. HUM- PHEEY, HELEN W. D. MTLEHAM, AND GUARANTY TRUST COMPANY, ADMINISTRA- Tons or EUGENE W. DURKEE, DECEAsED., Y y n APPARATUS FOR COVERING THE OPENINGS IN PERFORATED COVERS FOR CON- TAINERS WITH PAPER OR LIKE MATERIAL.

-1 n Application filed August 18, 1927. Serial No. 213,963.

My invention relates to covers for cans and other containers for holding ground or powdered material in which the covers are perforated for ksifting the material when desired, and the principal object of mygin* vention is to provide mechanical means for temporarily covering the perforations `in the covers, for transportation or when not in use.

It is very common in containers for ground orpowdered substances, to provide perforated covers fory sifting the contents when desired, such perforations being normally Closed by a disk provided with correspendingr perforations which may be rotated to bring' such perforations into register with the perforations in the cover propenbut such Construction is expensive, and to lessen such expense I am' aware that while it is not a common practice, 'in some instances a strip of l'iaper has been pasted Vover the perforations in the covers, which can be easily punctured to allow the contents of the containers to be sifted. To the best of my knowledge and belief, however, these papers vhave been applied t-o the covers by hand which isa slow and expensive practice. My invention provides an apparatus for applyingV such paper covering over the bei-fora-V tions in the container covers and consists in means for conveying the covers to position, means for applying adhesive to the surface of the covers, means for shifting the covers to position to receive the paper upon their glued surfaces, means for feeding;rv the paper from rolls, means for pickingJ up the forward ends of the Vfed paper bysuction, means for shutting' off the suction, means for cutting off strips of the picked up paper into the requiredsize to fit into or upon the covers. means for pressing such Cut off .strips of paper upon the glued surfaces of the covers, and means for carrying the cov# ers to a propeil receptacle after the paper has been so applied. The details of the construction and operation of` my new apparatus'are hereinafter particularly described.

`^ *Referring to the drawing, 10 denotes the bed of the machinesupported on vertical posts 11 the lower ends Arestfupon and are secured to a solid base 13 which 'is supportedby standards 12 as shown.`

The bed or table 10 is supported` at a height convenientfto'` the operator.

The' main drive shaft 14 is mounted vand supported in brackets 15, bolted or votherwise secured to the base 13 and is driven by the motor 17, a beltfltl.r passingT over a pulley 19, on the motor shaft 20, and over a pulley 21, secured. to the `drive shaft 14. The connection between the motor and drive shaft is controlledby a friction clutch 22 operated by the hand lever 23. The motor is supported by a bracket 24, fixed to the under side of the bed 10 or in any other suitable manner.` o

Three y'equally yspaced parallel arms or branches 25, S26 and 27,V extend horizontally fromthe bed l0 to which they may be seBJ cured in lany suitable manner but 'are preferably made integral therewith. These arms have flat vert-ical sides and kadjacent their outer ends are provided with aligned holes for the passage of a pin 28, there being a roller 29 loosely mounted upon this pin between the arms and 26 and another roller 30, being mounted in like manner between the arms 26 and 27. A conveyor belt- 31 for the covers 16, passes over the roller 3()r and through a slot in the bed 10, over another roller 32 iixed to a shaft 33 mounted'in bearings below the bed. A shaft 48 is idriven by a bevel gear 3-1 meshing with a bevel gear 35, driven by a chain belt- 36, passing over a sprocket wheel 37 and another sprocket wheel 38 mounted on a shaft 39 upon which is fixed a large gear wheel 40, meshing with a Ypinion 11, fixedrto a shaft 42 mounted in bearings y41.3 on the frame.

Fixed to the shaft L12, is a large gear wheel 141, meshing with a pinion 45, txed to the main drive shaft 111. A return belt 46 passes over tlre roller 29 and through the t slot in the bed over a roller 4T fixed to the shaft 18 mounted in vbearings below the bed which shaft is rotated in the opposite direction to the shaft 418 by a gear 4:9 uponr :1': recess the sides of the arms 25 26 and 27 extending higher than the tops of the belts,

forming guides for the covers 16,*which are placed upon the conveyor belt 31 by the operator at the forward end of the belt. denotes a disk provided with a central hub 61, having a hole through .its cent-er. To this hub on each side of the disk 60 is secured disks 62 and 63, respectively, each vprovided with a hole in alignment with the hole in the hub 6,1. These disks areloosely mounted on a pin 64 which passes through these holes and 1s supported in bearing in upright brackets 65 and 66 secured at their base to the' top of Vthe bed l0 by bolts 67 ,or in any other suitable way. The pin'64 is preferably provided with a knurled head 68 at one end.

A roll of paper 70 is mounted upon the hub `61 between the disks 60 and 62, and another roll of paper 71 is mounted upon the hub 61 between the disks 60 and 63. A guide roller 72 is loosely mounted upon a pin 73 supported in bearings in upright brackets 74 and?v 5, secured to the topfof the bed 10 yat their base by bolts or screws.

This roller 72 is reduced in diameter at each side of its central portion, with a disk 76 fixed to the end of each reduced'part, which parts .are in alignment with therolls of paper, the paper passing under the reduced parts of the roller 72 as it is drawn from the Vrolls 70 and -71by-rubber rollers v78 and 79 fixed to shafts 8O and 81, which '89 which works in a groove 90 in a cam wheel 91, driven from ythe shaft 39.

` AL shaft .is supported in `bearings in brackets 101 fixed yto the top of the bed 10 in any suitable manner, around which is ycoiled a spring 102, in alignment with each roll of paper. The upper projecting ends of these springs bear vagainst spring fingers 103, fixed at one end to the top of the brackets Y 101, and extending beneath and bearing v against each roll of paper to steady the rolls and prevent buckling as the paper is drawn 0E. f

The paper as it kpasses from between the rubber rollers 78 and 79 is received upon a plate 1014 supported upon the bed 10, which plate has adown-turned end 10,5, kwhich forms a cutting edge and as the paper reaches this point it lisl cut oif by a knife-106k into lengths of ya size to tit into or upon the covers 16. This knife is pivotally connected by a pin 1107 supported in upright brackets 168, fixed to the top of the bed 10 to an arm 110 being pivotally connected with a block 111, screwed upon the upper end of a vertical rod112, which passes through a hole in the bed 10. A nut 113 is screwed upon this rod 112 up against the lower end of the block 111 and surrounding the rod between this nut and the top of the bed is a spiral spring 114. The lower end of the'rod 112, extending beneath the bed, is screwed into the upper yend of arm v115 and secured by a nut 116. This'arm 115 is mountedl upon a shaft-117 which is supported in bearings upony brackets 118 boltedl to the under side of the bed y10. f y

On the .sha-ftrl'l'? is mounted a sprocket y119,r driven 'by aA chain 120 passing over a sprocket 121 fixed to'the shaft. 39. notes 'a fiat vertical shaft which passes through an opening in the bed 10 and extends a predetermiified distance arbore theY bed.

The lower end of this tlat shaft fits slidably into a vslot 123 in an upright bracket 1211, fixed to the base 13. Attached to the shaft 122, at or about itsk center, is a-'rod 125 "having a Vhub 1.26.y pivotally mounted on a bolt 127, which passes through a hole in the shaft and is secured by a lock nut 128.

AThe lower end vof 'the rod 125 is threaded which endis screwedv into an arm 120 and secured by a lock niit1'30. Adjacent. the lower `end ofthe arm129, there is attached a roll 131, which tits into a groove 132 in a lll!) branch 136.

cam wheel 133 mounted upon the shaft`39.

It will thus be seen that `while the ma.- chine is being operated, the Hat shaft 122 is given an up-and-down movement. Fixed to the upper Yend of the shaft 122, by screws or bolts,`is a bracket 134, having two spaced horizontal branches 135 and 136, which extend over the recess'in the top of the bed a predetermined distance and at a predetermined height above the bed'. Fixed into the Ylower end of the branch 135, there are two spaced pads o r blocks 137 of soft material, preferably sponge rubber` and similar pads 138 are fixed into' the lower end of the As the paper passes olf the edge of the plate 104 it is drawn'by suction up against the bottoms of the pads 137 in the branch 135, and is immediately cut off by the knife 106 which `at that moment is operated.

To accomplish this, l provide two spaced suction tubes 141 and 142, joined together by coupling nuts 143 and 144. These tubes extend through openings in the top of the branch 135, their lower ends being reduced in diameter and extending through the pads 137, nearly luShw-ith the bottom surface thereof.

The tubular end of the coupling nut 144 passes into one end of a flexible 4tube 145, the other end of which passes over the upper end of a metal tube 146, supported at 147, upon the back of the flat shaft 122. To the lower end of the tube 146 is connected another section of flexible tubing 148, the other end of which connects'with the upper end of another vertical Vmetallic tube 149, the lower end of which is screwed into the top of a valve chamber 150, which is connectedV at its lower end by a tube 151,"with a pump 152. This pump is operated by `a beltY 153, which passes over a pulley 154 fixed to the pump shaft 155 and over anotherA pulley 156, fixedto the drive shaft 14. The valve in the chamber 150 may be opened or closed by a cock 157, but ordinarily the suction is regulated automatically by the valve 150 coupled in the'line of tubing support-ed by a bracket 158, attached by screws or bolts 159, to the under side of the bed 10;

A collar 160 surrounds thelower end of i 'the valve casing which collar is provided other end of the link 162, is raised pressing theA valve .stenr164 upward opening the a hole in the bed with a lock nut l170, uponits lower end beneath the bed, said bolt being provided with a. flange 171, which rests upon thetop of the bed, the upper end of the bolt being threaded and passing through a hole in an angle piece 172, secured to, the rear end of the tank 168, therev being `a thumb nut 173 screwed upon the upper threaded end of the bolt, bythe removal of whiehthe tank may be lifted ofl' the bed for cleaningor other purposes. v 1

A glue roller 174'is positioned within .the tank 168, upon a shaft 175, mounted in bearings in the tank. Upon one ond Vof the glue shaft 175 is fixed a gear 176, meshing with a gear 177 on a shaft 178 upon which is also fixed the sprocket wheel 37, driven by the chain 36, passing over the sprocket wheel 38 on the shaft Two spaced parallel'arms 182 and 183 are supported a predetermined distance above thc bed 19 by brackets 184. The facing sides ofthe arms 182 and 183 are provided with longitudinal slots through which slide ribs 186 and 187iixed to a frame 188, in thc forward end of which is journalled a shaft 189 upon which is fixed two rubber rolls 196 and 191 which normally are in .contact with the glue roller` 174 by which` they are coated with the glue or other adhesive material. The rear end of the frame 188 is bentat right angles to the central part where it is again bent` at right angles forming ya slot 192, into which extends the upper end of a lever 193, pivotally connected. in the slot 192 by a bolt 194 to .the frame 188. This lever 193 is fulerumcd to a lug'195fixed to the upright 11 of the frame by a'bolt 196(r The lower end of the lever 193 is pivotally connected` by a'bolt 197 to 'one end of a rod 198, the other end of such rod being 'reduced lin diameter and threaded, which end is conattached to the forked member 199 which works in the cam slot 202 in the cam wheel frame 188zis continuously carried forward and backward'over theqbed whereby the rubber rolls 190 and 191 to which the glue or other adhesive has been applied lbythe glue roller 174 are carried underyand in 'Contact with. `the undersurlace of the pads `hile tl'ie machine is in operation, ,the` f 138, applying the adhesive thereto. Thev movements of the parts ai'e so timed that just as the rubber rolls 190 and 191 pass oli the pads 138 with the backward movement of the trame 18S, the shaft 122 descends by means of the mechanism hereinbefore described, and wheny said shait reaches its lowerinost position, the pads 138 come int-o contact with two oit the covers which have at that time come into position .under and in alignment with ysaid pads whereby the surfaceot each of said lcovers receives a coating o1' the adhesive carried by such pads. A push plate 203 attached to the` frame 188 pro-jects a predetermineddistance beyond the rubber rolls 190 and 191, and as the frame 188 moves forward the two covers which have previously received a. coating of the adhesive, are pushedby this plate into position under and in alignment with the pads 137 carried by the -suction tubes 141 and 142 and against which the cut oill sections ofv vat its bottom which enters a longitudinaly groove in a sliding rack 205. Upon one end oi this sliding rack is secured a casing 206, having a hole vin one end through whichy passes a pin 207 provided with ahead .20:8 at its upper end and with a knob 209 at its lower end. A plug 210 is lixed in the .outer end of the casing with another plug 211, concave on one side to contorni to the surface of the pin 207 in the other end of the casing and in contact with the pin, between which plugs there is a spiral spring 212 so that the pin is notrigidly held. A

rhere is an elongated slot in the bed 10 through which the head of the pin may ass.

A vertical rack .213 is secured to the s iaft 122 so that it moves upward and downward with such shalt. f

A. gear wheel 2141 is loosely mounted upon a lixed shaft 215', and secured tothe gear wheel 214L is a` small gear l21.6, which meshes with the vertical rack 213, the gear wheel 211 meshing with .the sliding rack 205. It will thus be seen that upon the `upward and downward movements of `the shaft 122, Athe rack 205 will be moved horizontally Abeneath the' bed 10, first in onefdirection and then the other. At one end of the trainey 204 is secured an inclined cam 217 and at `the other end of the frame is secured another inclined cam 218.

Upon the backward movement of the rack 205, the'knob 209 on thelower end of the pinV 207 rides over the top of the cam 217, rso that the head 208 of the pin is pushed up through theslot in the bed ydirectly be'- hind the covers which are atv that time under the pads 137, having received the strips of paper upon their glued surtaces by .the previous downward movement of the shaft 122. This position of the pin 207 is best ill-ustrated in F G. Upon the forward movement of the racly 205', the head of the pin 207r pushes the covers which have been thus treated oil `upon the deliverybelt 46 by which they are carried until they fall into any suitable receptacle provided for that purpose. As the head the pin 207 pushes the rcovers onto the delivery belt 16, the pin is drawn down by the Vknob 209 on its lower end passinga under the guide 218. This is best illustrated :in Figs. 5 and 7y of the drawings. v 1

l provide a handwheel 219 by which the sha'lit 42 may be rotated, should occasionV require. lt being preferable that' the paper be al plied to the under surface ot the covers. l have illustratedthe covers in an inverted position, but it will be apparent that the paper ycan Vbe applied in the saine way to the top surface .of the covers, if desired.
